The codes P0446 and P1441 came up on my 2002 Chevy Trailblazer and I was wondering what I can do to fix them.

You need a shop with a smoke machine, scan tool and voltmeter to test the system and determine the failure. Evap codes are tough to track down shooting from the hip.

Could part of it be that I need to replace the vent solenoid because I drive on dusty gravel roads everyday.
